SiDIS中极化$^3$ He靶态和终态相互作用
Polarized $^3$He target and final state interactions in SiDIS
摘要：
杰斐逊实验室（JLab）正在启动一项广泛的实验计划，旨在研究中子的结构，重点是提取部分子横向动量分布（TMD）。为此，半包容性深非弹性散射（SiDIS）实验极化$^3$他将进行，提供，连同质子和氘数据，一个健全的味道分解的TMD。考虑到预期的高统计精度，解开原子核和部分子自由度以获得初态和终态的精确理论描述是至关重要的。在这方面的贡献，在标准的SiDIS的末态相互作用（FSI）的初步研究，其中π介子（或K介子）被检测到在末态，鉴于构建一个现实的描述核的初始和最终状态。
英文摘要：
Jefferson Lab (JLab) is starting a wide experimental program aimed at studying the neutron's structure, with a great emphasis on the extraction of the parton transverse-momentum distributions (TMDs). To this end, Semi-inclusive deep-inelastic scattering (SiDIS) experiments on polarized $^3$He will be carried out, providing, together with proton and deuteron data, a sound flavor decomposition of the TMDs. Given the expected high statistical accuracy, it is crucial to disentangle nuclear and partonic degrees of freedom to get an accurate theoretical description of both initial and final states. In this contribution, a preliminary study of the Final State Interaction (FSI) in the standard SiDIS, where a pion (or a Kaon) is detected in the final state is presented, in view of constructing a realistic description of the nuclear initial and final states.
